What is the suggested cause of metatarsus adductus?

The suggested cause of metatarsus adductus is often linked to the infant's position inside the womb. This condition is characterized by a bending of the foot inward and is believed to result from the limitations in space that come during fetal development. When a baby is positioned in a way that places excessive pressure on the feet, particularly if they are in a breech position or if there's restricted amniotic fluid, it can lead to this condition. The shape of the uterus and the surrounding structures might also contribute to how the foot develops prenatally.

While genetic predisposition can play a role in many congenital conditions and there may be associations with certain maternal factors, the mechanical and positional influences during fetal development are primary in the etiology of metatarsus adductus. Premature birth and growth restriction are relevant to numerous neonatal conditions but are not closely associated with metatarsus adductus specifically. The primary focus regarding this condition is the mechanical environment within the womb rather than genetic or developmental timing factors.
